Tank Bottom Diaphragm Valve<\/h3>\n

Key Features<\/h3>\n

\u2022 The tank bottom diaphragm valve (also referred to as a vessel outlet valve or drain valve) is specifically designed for installation at the lowest point of process vessels, tanks, fermenters, and bioreactors.
\n\u2022 Its primary function is to enable complete, hygienic, and sterile drainage of process fluids without leaving residual product in the vessel.
\n\u2022 The valve features a short-bottom connection with minimal dead leg, compliant with the Institute of Brewing (IOB) and EHEDG guidelines for vessel drainage.
\n\u2022 The short-bottom nozzle extends slightly into the vessel, creating a flush internal profile that prevents product accumulation at the tank bottom.
\n\u2022 This valve is an indispensable component in pharmaceutical bioreactors, food processing vessels, brewing tanks, and dairy storage silos where complete product recovery, sterile drainage, and cleanability are paramount.<\/p>\n
